Satellite makes right whale count

Scientists have demonstrated a new method for counting whales from space, using a very high-resolution satellite and image-processing software to automatically detect the great mammals at or near the ocean surface.

A test count conducted on southern right whales in the Golfo Nuevo on the coast of Argentina found about 90% of the creatures pinpointed in a manual search of the imagery.

Peter Fretwell from the British Antarctic Survey is behind the work, which he described to Lucie Green on Inside Science on BBC Radio 4.
